SUCTION OR BLOWDN'G APPARATUS.

Patented May 10, 1921.

Application fi led November 17, 1920. Serial No. 424,596.

To all whom it may concern:

Be it known that I, IRA H. SPENIJER, a

citizen of the United States, and a resident of West Hartford, in thecounty of Hartford and State of Connecticut, have in-. vented new andImproved Suction-or Blow ing Apparatus, of which the following is aspecification.

My invention relates to the class of apparatus for creating air currentsfor blowing or suction purposes, and an object of my invention. amongothers, is to provide a device of this class that shall be simple andcomparatively inexpensive to construct and the operation of which shallbe particularly effective.

One form of apparatus embodying my invention and in the construction anduse of which the objects herein set out as Well as others, may beattained, is illustrated in the accompanying drawings, in which Figure 1is a view partially in side elevation and partially in central vertical1ongitudinal section through my improved apparatus.

Fig. 2 is a view in cross section on plane denoted by dotted line 2-2 ofFig.1.

Fig. 3 is a view of that end opposite the motor, with parts broken awayto show construction.

My improved apparatus as illustrated and described herein is formed inthree sections, a motor section 5, a fan section 6, and an intake orvalve section 7, all of which sec tions are made from sheet metal andwhich sections are secured together in any suitable manner.

The motor section 5 comprises two sides 8 formed from sheet metal andhaving sloping upper edges 9, outturned flanges 10 at the back edges,and hand holes 11 through which access may be had to the interior forany desired purpose.

A bottom plate 12 extends across the structure between the side partsand is secured thereto in any suitable manner, as by electric welding,and a motor supporting plate 13 extends between the side parts and hasdown-turned flanges 14 providing a means for securing this support tothe side parts, as by electric welding or in any other suitable way. Amotor 15 rests upon said cylindrical shape with partially closed ends 18and 19, one of which ends has a small central hole for the motor shaftand the other of which endshas a much larger hole 20 to receive thecasing of the valve section 7. Both of said ends have flanges 21extending toward each other when the ends are in place and the barrel 17is encircled by these flanges, the ends of said barrel resting againstthe faces of said ends 18 and 19 and is suitably secured in place as byelectric welding or otherwise. All exhaust opening 22 is formed throughthe side of the barrel and an. exhaust nipple23 is secured to the barrelsurrounding said exhaust opening as a means for conducting exhaust fromthe barrel.

-A diaphragm 24 extends across the barrel, dividing it crosswise, thisdiaphragm having a flange 25 resting against the interior ofthe barrelas a means of support for the diaphragm and which diaphragm has an eye26 for theflow of air to the fan and exhaust chamber 27 located betweenthe diaphragm and that end of the barrel next to the motor section. Anopening through this end of the motor section is suitably packed againstflow of fluid, as by means of a packing 28 of fibrous material held inplace as by means of apacking plate 29 secured as by means of bolts. Adiverting plate 30 ismounted on .the shaft 16 to divert any slight flowof fluid through. the shaft hole and thereby prevent its access to'oilwithin the shaft bearing and consequent removal of such oil from thebearing. l

Fluid directing vanes 31, preferably 'of curved form, are secured in anysuitable manner with their edges against the diaphragm 24, these vanesextending from the inner surface of the barrel to the edge of the eye26, and a return chamber plate 32 is secured to the edges of said vanesto provide a returning chamber 33, this plate being smaller than thediameter of the barrel 17 to provide an annular opening 34 from theinlet chamber to the return chamber 33. A hole is formed in the centerof the return chamber plate for the shaft 16, and'a packing is suppliedat this hole as hereinbefore set out with respect to the hole throughthe end 18. I

Fans of any suitable construction are secured to said shaft Within theinlet chamber 35 and the exhaust chamber 27, as shown opening or eye 43.

herein these fans comprising each a base 36 with a hub 37 thereofsecured to the shaft 16, a blade plate 38 secured to the base, blades 39with their back edges secured to said plate and their front edges havinga front plate This valve section is inserted through the opening 20 intothe inlet chamber 35 to such extent as may be desired and depending uponconditions of construction and special use to which the apparatus may beput, in which position said section is secured in any suitable manner,this insertion of the tube when the flange of the'end thereof is on theoutside being made before the plate 42 and the end 19 are finallysecured in place. A lining 44 is secured to the inner surface of thevalve section and the valve, in the form shown.

herein comprising two flaps 45, is mounted to control the inlet opening,said flaps being preferably spring pressed into their closed positions,the spring, however, being insufficient to prevent opening movement ofthe fluid into the inlet opening 46.

I claim k 1. A suction or blowing apparatus casing comprising a motorsection with Sides arranged in spaced relation, a motor supporting plateextending between the side parts and secured thereto, and a fan sectionhaving an end with its flat face secured against the back edges of saidsides.

2. A suction or blowing apparatus casing comprising a motor section withsides arranged in spaced relation, a motor supporting plate extendingbetween the side parts and secured thereto at a distance from the bottomedges of the side parts, a bottom plate secured to the bottom edges ofthe side parts and extending across them, and a fan section having anend with its flat face secured against the back edges of said side.

3. suction or blowing apparatus casing comprising a motor section withsides arranged in spaced relation, a motor supportflaps under the forcecaused by the flow of and having turned flanges with their sides'secured against the faces of the side parts at a distance from thebottom edges thereof, a bottom plate secured to .the bottom edges of theside parts and extending across them, and a fan section having an endwith its flat face secured against the back edges of said sides.

4. A suction or blowing apparatus casing comprising a motor section, afan section separately formed from the motor section and comprising abarrel with an end plate having its flat face secured against the motorsection, a diaphragm secured to the inner surface of the barrelandextending there across, directing blades secured with their edgesagainst said diaphragm, a plate secured against the opposite edges of,said blades, and a closure for the end of the barrel.

5. A suction or blowing apparatus casing comprising a motor section, aseparately formed fan section secured to the motor section, andsupported thereby and including an end plate, and a valve sectioncomprising a barrel inserted through said end plate and secured therein.

6. A suction or blowing apparatus casing comprising a motor section, aseparately formed fan section supported by the motor sectionandincluding a barrel and end plates having flanges to receive said barrel,one of said end plates being secured withits flat plates having acentral opening, and a valvesection comprising a barrel inserted throughsaid opening and projecting into an inlet chamber within the fansection, said valve section comprising a barrel with an end plate Yhaving a flange to receive said barrel.
